Abstract: 1,104,264. Valves; alternative power and manual actuation of a member. PHILIPS PATENTVERWALTUNG G.m.b.H. 27 May, 1965 [30 May, 1964], No. 22579/65. Headings F2L and F2V. Operation of a power unit 2, e.g. an electric motor, actuates an element, such as a valve, through a pawl 12 engaging a recess 4 in a disc 3 on the unit 2, a lever 7 on which the pawl is pivoted, a setting member 5 rigidly connected to the lever, and a crank 6; the lever 7 follows the movement of the member 5 and serves as a position indicator. Should the power unit 2 fail, the element can be manually actuated by depressing a spring- urged button 8 to disengage the pawl 12 from the disc 3 and then positioning the member 5 by the lever 7; when the button is released the pawl enters one of a number of recesses 14 in a fixed part 13 to lock the lever and hence the setting member. When the power unit restarts and has rotated sufficiently to correct its deviation from the control cycle the recess 4 is aligned with the pawl 12 which snaps into the recess to recouple the unit to the element. The unit is provided with a device, e.g. two sets of contacts, to effect reversal of the power unit should it restart in the wrong direction.
Patent GB-230120-A (GB)
Title: Improvements in and relating to photographic and projection systems for obtaining stereoscopic effects
IPC: G03B35/00
Filed: 1923-09-08
Abstract: 230,120. Wright, E. H. Sept. 8, 1923. No Patent granted (Sealing fee not paid). Enlarging, copying, and reducing.- Stereoscopic effects in kinematographic projection are secured by projecting related views in super-position on the screen and causing one set to dissolve or fade simultaneously with the gradual increase in luminosity of the other set over a series of images in such a manner that the dissolving or fading out of one set is complete when the corresponding image of the other set is at its maximum luminosity. This dissolving effect is produced by the rotating of a shutter of gradually increasing opacity. Alternatively, the photographs may be superimposed in the camera or when producing the film for projection from two negative films. In each case one set is gradually dissolved or faded out, while the other set increases in luminosity. An ordinary projector may then be used for the film thus produced. In taking the photographs in superposition a graded screen e, is mounted between the objectives a, a<1> and a lens c. The screen is transparent at the end e<2> of one diameter and opaque at the other end e<1>. The screen e rotates during the passage of several picture spaces, the exposure being effected by the shutter f. A mark d having two apertures d<1>, d<2> is placed over the lens c whereby the two images are superimposed on the film b. In a modified form of screen a number of opaque portions alternate with the graduated portions so that an exposure shutter may be dispensed with. In the example shown in Fig. 4, the right and left hand pictures b<2>, b<1> have been produced upon a film one above the other and are projected in superposition on the screen h through the graded screen l, by means of a lens i for the left hand picture and an adjustable rhomboidal prism and a lens for the right-hand picture. The graded screen is not used in projection when the pictures have been taken with the aid of such a screen although not superposed on the film. Several other methods of producing the film are described all involving the use of the rotating graded screen, such as a printing machine operating in a manner similar to that of the projector shown in Fig. 4, and the photographing of superimposed pictures projected on to a screen.
